Electrical & Wiring Instructions; Start-Up & Operation - GRE VSG75 Instruction Manual

3. ELECTRICAL & WIRING:
WARNINGS
– Ground and bond motor before connecting to electrical power supply. Failure to ground and bond pump mo-
tor can cause serious or fatal electrical shock hazard. See Grounding and Bonding instructions.
– Do NOT ground to a gas supply line.
– To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.
– Ground Fault Circuit Interrupter (GFCI) tripping indicates electrical problem. If GFCI trips and won't reset,
consult electrician to inspect and repair electrical system.
– Fire Hazard.
Match supply voltage to motor nameplate voltage. Insure that the electrical supply available agrees with the
motor's voltage, phase, and cycle, and that the wire size is adequate for the H.P. (KW) rating and distance from
the power source. NOTE - All electrical wiring MUST be performed by a licensed electrician, and MUST con-
form to local codes. Use copper conductors only.
VOLTAGE
Voltage at motor MUST NOT be more than 10% above or below motor name plate rated voltage, or motor may
overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than 110%
of rated voltage when motor is running at full load, consult Power Company.
GROUNDING AND BONDING
Install, ground, bond, and wire motor in accordance with local or national electrical code requirements. Perma-
nently ground motor. Use green ground terminal provided under motor canopy or access place; use size and
type wire required by code. Connect motor ground terminal to electrical service ground. Bond motor to pool
structure. Bonding will connect all metal parts within and around the pool with a continuous wire.
Bonding reduces the risk of a current passing between bonded metal objects, which could potentially cause
electrical shock if grounded or shorted.
4. START-UP & OPERATION:
PRIOR TO START-UP
Notice: If it is necessary to perform a pressure test, prior to initial use to ensure pump is functioning properly,
then the following criteria should be maintained for this test:
1. Have a professional perform this test.
2. Ensure all pump and system components are sealed properly to prevent leaks.
3. Remove any trapped air in the system by fully opening filter manual air relief valve until a steady stream of
water is discharged.
4. Allow no more than 40 psi (276 kPa) at a water temperature no higher than 40C0.
5. Run pressure test for no longer than 24 hours. Immediately inspect all parts to verify they are intact and
functioning properly.
Fill strainer housing with water to suction pipe level. NEVER OPERATE THE PUMP WITHOUT WATER. Water acts
as a coolant and lubricant for the mechanical shaft seal.
WARNING – If pump is being pressure tested (40 PSI MAXIMUM), be sure pressure has been released before
removing strainer cover.
CAUTION – NEVER run pump dry. Running pump dry may damage seals, causing leakage, flooding, and voids
warranty. Fill strainer housing with water before starting motor.
ATTENTION – Do NOT add chemicals to pool system through the skimmer (if pool is so equipped) or directly in
front of pump suction. Adding undiluted chemicals may damage pump and voids warranty.
ATTENTION – Before removing strainer cover:
1. STOP PUMP before proceeding.
